Takata recall; received air bag recall 2014, took to david maus Toyota sanford, florida and had passenger air bag corrected with my receipt. 2016 June, air bag warning light was on, (noticed while driving) took again to david maus Toyota, they found error code and checked all diagnostics, found nothing wrong. The simply diagnosis couldn't determine the cause and then was advised to pay for a thoroughly diagnosis, which I payed $128. 00. Today July 2nd while driving truck, found air bag light on again (while driving) !! I spoke to david maus Toyota service manager July 2nd. He said I can bring it in again and my $128. 00 dollars would go to any needed repairs. I'm taking my 2004 Tundra truck in, either July 5, 6, or 7th.
